Authorities are searching for a 14-year-old girl after her stepfather was found dead along a county road in northeast Arkansas.

Arkansas State Police say Sidney Nicole Randell hasn't been seen since about 10 p.m. Saturday.

Walnut Ridge Police Chief Ricky Thatcher says the body of her stepfather, John Carnell, was found Monday about 100 yards from his truck outside town. Thatcher says a pistol was found nearby. He says officers are treating it as a suicide but stressed the investigation is ongoing.

Sidney Nicole is 5-foot-4, weighs about 85 pounds and has brown, shoulder-length hair and green eyes. She was last seen wearing a brown Aeropostale jacket.

Thatcher says his officers had never been called to the family's home in Walnut Ridge, about 130 miles northeast of Little Rock.
